    The last statement is incorrect.
    The clear'ness of the property can be found with the builtin function:
      is_clear_property(OBJ, "property")
    And you can make a property clear with the builtin function:
      clear_property(OBJ, "property")
    When a property is 'clear', the value of that property on the object's
    parent is shown.
